Determine the variance
Variance (Var) is calculated as follows;
Substitute values for n and p
Convert percentage to decimal
<em>Hence, the variance is 2.64</em>
33 years old would be correct
The answer is D. Y = 63 + 2 = 65
The given equation is y = x + 2, the height is given as 63. The height is the x value so you would replace x in the equation with 63 and solve for y.
Answer:
6 times 2 = 12
